At present, the Internet focuses on traffic and storage. With the development of the world, bt network was born, which is a distributed storage and traffic system. But it also has its limitations. First, the bt network can only transmit and share a single file. Secondly, there is no incentive mechanism in bt network. To put it simply, people have joined the bt network, but they have no intention to actively save and distribute files, because it is not good for participants.
With the exposure of bt network defects, IPFS was born. That is, the IPFS system developed by the protocol laboratory of Filecoin project. IPFS is an upgraded version of bt network. It joined the folder system on the basis of bt network. In the IPFS system, folders can be directly transferred and shared. Others can also browse related data and files directly from the folder.
But IPFS, like bt network, has several problems. First, there is no incentive system. Second, in the initial stage of file transmission, because there are few nodes storing files, the efficiency is very low. For example, if A uploads a file and B needs to retrieve it, then it can only be retrieved from A .. so the efficiency is very low. If C wants to retrieve, it can only be retrieved from nodes A and B. If both A and B are closed, the file cannot be retrieved. This is a problem with IPFS and bt networks. Their initial transmission efficiency is extremely low. Only when files are searched for countless times and widely distributed in nodes, the transmission speed will become very fast. So bt network and IPFS system, they are both a process from slow to fast. If you retrieve a file with a small distribution ratio among nodes, the retrieval ability is very weak and the transmission speed is very slow. In order to solve the problem of this incentive mechanism, the protocol laboratory developed a supply chain called Filecoin.
Filecoin and IPFS are two concepts. Filecoin actually moved the real IPFS to the blockchain. Blockchain is characterized by decentralization, mutual distrust between nodes, and data transmitted between nodes must be rechecked. This has led to poor performance of the blockchain. Filecoin was founded after IPFS was injured. Therefore, Filecoin is also affected by the performance of blockchain, so it can't match valid data and can't achieve efficient retrieval. Filecoin realizes data storage on the blockchain, which is a very significant contribution. Then SWARM and BZZ appeared, but BZZ has only one flow settlement system because there is no blasting incentive mechanism, which seems to be a failure at present. However, compared with IPFS and Filecoin, BZZ has also made some improvements: a set of active distribution mechanism. For example, if I upload a video, the video will be actively distributed by the node. The video will be quickly cached to multiple nodes. Therefore, BZZ has made outstanding contributions in traffic settlement and efficient retrieval. Although it left a technical contribution, it was still a failed project.
At present, transportation and storage have solved most of the problems in the blockchain field. The second is the performance of the blockchain. After years of evolution, Layer0, Layer 1 and Layer2 have also undergone constant experiments. In recent years, many achievements have been made in the field of Layer 1, including patents. I believe that the breakthrough of high-performance public chain will appear soon.
Therefore, if you want to build a blockchain network that is really similar to web3, you should achieve three breakthroughs: First, efficient retrieval. Second, encourage the separation of storage and traffic. Third, there must be an authorized access system. Authorized access system is similar to watching video websites, and you need to pay to get data. In the world of traditional Internet, there are many channels for realizing it. The Internet world of blockchain has just taken shape. Therefore, ecological builders can directly obtain certain benefits. Only in this way can we promote ecological prosperity and let ecological builders continue to contribute more useful applications. Finally, the breakthrough of high-performance public chain is also an essential link. So, with the above four conditions, web3 is getting closer and closer to us.
